I have always used their web app (even on mobile, i just use their pwa instead of the native app since the native app is missing obvious features), and I haven’t had any issues, but I can definitely understand the frustration if you want to use anything else. OP, keep that in mind if you’re thinking about Proton!
I don’t speak French natively but I happen to know their version of lol is “mdr”, short for mort de rire (dying of laughter)
